Acritus komai
clown beetle
Acritus komai is a small clown beetle (family Histeridae) described by Lewis in 1879. The species exhibits a remarkably broad geographic distribution spanning Africa, Europe, Asia, North America, and Oceania. It belongs to the subfamily Abraeinae, a group of diminutive histerids often associated with decaying organic matter. The species name honors a person, following the Japanese surname 'Komai'.
Aeletes
clown beetles
Aeletes is a genus of clown beetles in the family Histeridae, established by Horn in 1873. The genus contains more than 80 described species. These beetles belong to the subfamily Abraeinae and tribe Acritini. Species in this genus are small histerid beetles with limited documented ecological information.
Halacritus
Halacritus is a genus of clown beetles (family Histeridae) established in 1893. The genus contains more than 20 described species. Members of this genus belong to the subfamily Abraeinae and tribe Acritini. These beetles are part of the diverse histerid fauna, though specific ecological details for the genus remain poorly documented.
Halacritus maritimus
clown beetle
Halacritus maritimus is a species of clown beetle in the family Histeridae, first described by John Lawrence LeConte in 1851. The species is distributed in North America, with records from California and potentially other regions of the United States. As a member of the Histeridae, it belongs to a family of beetles commonly known as clown beetles or hister beetles, characterized by their compact bodies and clubbed antennae.
Plegaderus
clown beetles
Plegaderus is a genus of small clown beetles in the family Histeridae, established by Erichson in 1834. The genus contains more than 30 described species. These beetles belong to the subfamily Abraeinae and tribe Plegaderini. Members are found primarily in the Northern Hemisphere, with records from Denmark, Norway, and Sweden.
Plegaderus sayi
clown beetle
Plegaderus sayi is a species of clown beetle in the family Histeridae, first described by Marseul in 1856. The species occurs in North America, with documented records from Canada and the United States. Like other members of Histeridae, it belongs to a group commonly known as clown beetles due to their habit of feigning death when disturbed. The species is part of the subfamily Abraeinae, a lineage of small to minute histerid beetles.
Teretrius latebricola
clown beetle
Teretrius latebricola is a small histerid beetle described by Lewis in 1901. The species is currently treated as a synonym of Aymericetrius latebricola by some taxonomic authorities, though both names remain in use across different databases. It is recorded from eastern North America, with observations from both Canada and the United States. As a member of the Abraeinae subfamily, it belongs to a group of minute histerids often associated with decaying organic matter.
Teretrius placitus
clown beetle
Teretrius placitus is a small clown beetle in the family Histeridae, first described by Horn in 1880. The species belongs to the subfamily Abraeinae, a group characterized by minute body size and reduced elytra. It is known from limited collection records in the southwestern United States, specifically Nevada. As with most Teretriini, detailed biological information remains sparse due to its cryptic habits and small size.
